Hey,
With an asynchronous connection, download speeds can be affected by heavy upstream activity. This occurs because after you recieve a TCP packet, you are supposed to send an ACK back to verify that you have recieved it. If your upstream is saturated, the ACK gets queued and if it taked to long to get it out, it screws up the download.

The document: http://www.benzedrine.cx/ackpri.html describes a method for fixing this problem in OpenBSD. Basically, he sets the computer to prioritixe the ACK instructions in the TCP queue. My question is, is this possible in OS X? How?

Thanks!

PS: I cross-posted this is OS X, Unix, and Networking. Feel free to lock/delete if this is a breach of etiquette.
